This is where we enter workstation territory. In a workstation there are at least two sockets on the motherboard for two or more CPUs and each CPU has a dedicated pathway to its own memory bank. So for example, if each CPU is made up of 4 cores, you have 8 processing units in one computer. Workstations with this sort of CPU power are essential for 3D modeling applications as used in architecture, engineering, and medicine. They are also used for 3D video and broadcast-quality rendering because they require a huge number of calculations that only this number of processors working simultaneously can provide.
Because of the size of the files, workstations in this category take up to a maximum of 32GB of memory, or 16GB of memory supporting each CPU.
Hard Drives are configured in RAID that is in groups of two or more since this gives significant performance and redundancy advantages over using hard drives singly. Hardware RAID is strongly recommended over the RAID controller found on the motherboard because the former are usually of much higher quality.
The best video cards for this work are professional grade cards that have been thoroughly tested to run reliably with these types of applications, hence their significant price premium. Unlike consumer gaming cards, they are specifically developed to give the best possible image and trouble-free operation for 3D modeling and video rendering.
